Demon
Inline
Twins for Blower
Applications
--- the first
to be boost-
referenced Supercharged?
Have you ever wondered how
to make blower carburetors
respond instantly? |
|
 |
|
|
The
answer is boost-referencing. By being properly
boostreferenced, the power valves in the carburetors
become load-sensing devices and respond instantly
to the demands of the supercharged engine.
Further, with eight venturi bores aligned with
their corresponding intake runners, these Demon
Inline Twins offer excellent fuel distribution
and atomization. They also eliminate hesitation
and surging, and promote a stable idle and crisp
throttle response.
- Available
in 525, 625, and 725 CFM models, Demon In-line
Twins are the first of their kind to be boost-referenced
for Roots-style superchargers

secondary throttles for street and highway
use

- Compact,
side-hung fuel bowls with sight glasses for
safe, easy float-level adjustment

direct replacements for the Holley 1850, the
Inline Twins are easy to install and tune

appearance, stunning performance, and surprisingly
good fuel economy
- Two-corner
idle adjustment with secondary metering plates
standard; electric choke optional
- Wet-flow
tested and baseline calibrated at the factory,
each carburetor is shipped with a detailed
tuning manual
